Использование физиологически активных веществ для увеличения ростовой активности сельскохозяйственных и декоративных растений

Abstract

The effect of organic compounds synthesized at the Department of Organic Chemistry of Voronezh State University on the sowing qualities and growth performance of the deciduous shrub Rhododendron yellow (Rhododendron luteum Sweet) and sugar beet (Beta vulgaris L.) was studied. The purpose of the work was to identify the effects of 6-hydroxy‑2,2,4-trimethyl‑1,2- dihydroquinoline and its derivatives on the growth activity of Rhododendron yellow and sugar beet. Treatment of uncoated sugar beet seeds with an aqueous solution of 6-hydroxy‑2,2,4- trimethyl‑1,2-dihydroquinoline increased the seed germination energy by 37–46%, the seed germination by 32–40%, average seedling length by 53–94%, and the weight of 100 seedlings by 69–125% compared to the control. Dihydroquinolines and, to a lesser extent, tetrahydroquinolines may be considered more effective substances in the early stages of development of Rhododendron luteum. The compound 6-hydroxy‑2,2,4-trimethyl‑1,2-dihydroquinoline had a positive effect on the growth activity of Rhododendron yellow and sugar beet. The sowing qualities and growth traits of the plants studied significantly improved under the effect of synthesized organic compounds.
